ELEAZER KEMPSHALL, OF BOSTON, MASSACHUSETTS.

PLAYING-BALL.

SPECIFICATION forming part of Letters Patent No. 713,770, dated November18, 1902.

Application filed June 14, 1902. Serial No. 111,767. (No model.)

To all whom it may concern:

Be it known that I, ELEAZER KEMPSHALL, a citizen of the United States,residing in Boston, in the county of Suffolk and State of Massachusetts,have invented certain new and useful Improvements in Playing- Balls, ofwhich the following is a specification.

This invention relates to playing-balls, such as used in golf and othergames; and its object is to improve their construction, durability, andefficiency.

In the drawings forming part of this specification, Figure l is a viewof the completed ball, partly broken away to disclose its construction.Fig. 2 is a section of the ball, showing the hemispherical segmentallayers of fabric and of gutta-percha applied to the core and theunmatched joints of the various segments.

In the several views similar parts are designated by similar charactersof reference.

Upon a core or filling A, of suitable material, such as soft rubber, Iapply a shell 13, composed of layers of fabric alternating with layersof gutta-percha, the fabric being designated by 1, 3, and 5 and thegutta-percha by 2, 4:, and 6, respectively. These layers are preferablymade up into hemispherical segments or cups and are applied to the coreA so that the joint between the segments of one layer will be sodisposed as to cross the joint of another layer, so that when all of thelayers are applied to the core the several joints between each shellwill be staggering, as illustrated in Fig. 2. After applying the elastichemispherical segments 2, 4L, and 6 and the fabric hemispherical layers1, 3, and- 5 in alternation the ballis placed between suitableheating-dies, whereby the fabric layers of the shell are embedded in theplastic segments, and owing to the staggering relation of the jointsbetween the several successive layers the whole will be without a jointthat extends through more than a single layer, thus increasing thedurability of the shell and preventing it from bursting. It will be seenthat by this construction and method of application of the shell thejoint between each layer,whether of fabric or gutta-percha, isreinforced by the succeeding as well as the preceding layer. Hence theliability of bursting of the shell at any point when struck by animplement is overcome.

Having described my invention, I claim- A playing-ball comprising asolid sphere of soft rubber and a plurality of layers of fabric thereonalternated with a plurality of layers of gutta-percha, each of saidfabric and gutta-percha layers consisting of hemispherical segments, andthe joint between said segments in each of said layers crossing thejoint in the adjacent layer or layers.
